This standard specifies the protocol on the Studio-to-Transmitter Link (STL) from studio-side infrastructure to a Single Frequency Network (SFN) of Transmitters. It defines delivery protocols for ALP Transport. The document also defines possible interfaces among the studio infrastructure, for example the interconnection of the ATSC 3.0 Link Layer Protocol (ALP) and a Broadcast Gateway. This document specifies certain constraints on the scheduling of content and signaling on the Physical Layer. The described scheduling process enables Preamble generation and emission time management. It specifies certain aspects of Transmitter behavior and certain parameters of Transmitter operation.
A Candidate Standard revision of A/324 is available that may be helpful to implementers. Please see the ATSC 3.0 Candidate Standards page.
